Review on πŸ”§ OptiCenter Woodworking Precision Drilling Replacement by Mike Davis

Revainrating 5 out of 5

They are FLAT on the bottom

They are not "self centering". If the outside diameter matches the hole, good. But what I usually want is a cone shaped bottom centered in a hole of about the right size. Not this one.

Pros
  • Hex Shank Drill
Cons
  • They could have chosen a newer model
